S7017 ACB/P4A Bearing Product Overview & Core Advantages
The S7017 ACB/P4A is a single-row angular contact ball bearing designed for applications requiring high precision and superior rigidity. Engineered to a P4 (ABEC-7) tolerance class, it delivers exceptional running accuracy. This bearing is optimized to handle combined loads (radial and axial) simultaneously, with its 25° contact angle providing excellent axial load capacity. It comes preloaded for immediate high-stiffness performance and is pre-lubricated and sealed, making it a ready-to-install, low-maintenance solution for demanding industrial environments.
S7017 ACB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | S7017 | Denotes a high-precision angular contact ball bearing series with specific internal geometry. |
| Contact Angle | ACB | Indicates a 25° contact angle, balancing radial and axial load capacity. |
| Tolerance Class | P4A | Signifies a P4 (ABEC-7) precision grade, ensuring extremely tight dimensional and running accuracy. |
S7017 ACB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Preload: The bearing is supplied with a preload, which eliminates internal clearance. This significantly increases system stiffness, reduces vibration, and improves positional accuracy, which is critical for high-precision applications like machine tool spindles.
- Superior Load Capacity: The 25° contact angle and optimized raceway design enable the bearing to efficiently support combined radial and axial loads. With a dynamic load rating of 5648 lbf and a static load rating of 5040 lbf, it is built for durability and long service life.
- High-Speed Capability: The lightweight phenolic resin cage minimizes centrifugal forces and ensures stable operation, contributing to a high limiting speed of 12,000 rpm. This makes it an excellent high-speed bearing.
- Sealed & Lubricated for Life: As a sealed unit with factory-applied lubrication, it is protected from contamination and is designed for maintenance-free operation within its specified temperature range (-30° to 110 °C).
S7017 ACB/P4A Bearing Typical Application Areas
This bearing is ideally suited for high-performance machinery where precision, speed, and reliability are paramount. Key applications include:
- Machine Tool Spindles (milling, grinding, and lathe centers)
- High-Frequency Motors and Spindle Drives
- Precision Gearboxes
- Industrial Pumps and Compressors
- Robotics and Automation Equipment
